michael@0: * {@code ToolbarDisplayLayout} is the UI for when the toolbar is in

michael@0: * (updateFromTab) and should never track any tab events or gecko messages
michael@0: * on its own to keep it as dumb as possible.
michael@0: *
michael@0: * The UI has two possible modes: progress and display which are triggered
michael@0: * when UpdateFlags.PROGRESS is used depending on the current tab state.
michael@0: * The progress mode is triggered when the tab is loading a page. Display mode
michael@0: * is used otherwise.
michael@0: *
michael@0: * {@code ToolbarDisplayLayout} is meant to be owned by {@code BrowserToolbar}
michael@0: * which is the main event bus for the toolbar subsystem.
